Authorities in Connecticut release investigation documents in the Sandy Hook school shooting.

(NBC News) Police in Connecticut released thousands of pages of documents Friday from the investigation into last year's school massacre at Sandy Hook Elementary School in Newtown, which could shed additional light on the world of the 20-year-old gunman.

The paperwork "has been redacted according to law," and it includes text, photos, videos and recordings of 911 calls received by state police.

In a letter accompanying the report, Reuben F. Bradford, commissioner of the state Department of Emergency Services and Public Protection, wrote that much of the identifying information involving children and many witnesses were withheld, as were "all visual images depicting the deceased."
